DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure. See also Figure 1-Figure 7 The present embodiment provides a welding tool for automobile seat accessories, comprising a workbench 1, a turntable 2 is rotatably arranged on the workbench 1, a driving device is arranged on the workbench 1 to drive the turntable 2 to rotate, a guide plate 21 is fixedly connected to the turntable 2, and a plurality of welding heads 22 are arranged on the turntable 2; a storage tank 3 is also arranged on the workbench 1, a fixed tube 31 is fixedly connected to the bottom of the storage tank 3, a guide assembly is arranged in the fixed tube 31, when the screw enters the guide assembly, the rod of the screw is driven vertically downward by the guide assembly; a limiting assembly is also included, when the storage tank 3 is working, the limiting assembly is driven to rotate to intermittently limit the screw, so as to be used for the output welding of the screw at the bottom, after welding, heat is generated in the fixed tube 31, and the screw at the bottom is pre-set Heat is used to eliminate the stress inside the screw, reduce the deformation and cracks caused by welding, and improve the fatigue strength and corrosion resistance of the weld; the screws are injected into the storage tank 3, and then fall one by one through the funnel 51 between the two rotating rods 52, and then the rotating rod 52 is set to an inclined surface so that the tip of the screw is transported downward to the fixed tube 31, thereby realizing adaptive adjustment of the direction of the tip of the screw. During welding, the fixed tube 31 contacts the slide rail, and then the guide assembly is driven to rotate so that a single screw is output and falls into the change joint, and the screw is welded to the slide rail through the welding head 22. The rotating rod 52 is driven to rotate by the rotation of the guide assembly, and the sliding of the auxiliary screw on the rotating rod 52 is realized to realize the single delivery of the screw, and the automatic loading and arrangement of the screws are realized.

[0022] In an embodiment further provided by the present invention, the limiting assembly includes a rotating tube 41 rotatably arranged outside the fixed tube 31, and two limiting plates 42 are fixedly connected to the outside of the rotating tube 41. The two limiting plates 42 both extend into the fixed tube 31. The two limiting plates 42 are arranged in an irregular shape, and the two limiting plates 42 are staggered. When the fixed tube 31 is suspended in the air, the limiting plates 42 limit the fixing and prevent it from falling. When the fixed tube 31 is welded, the limiting plates 42 unlock the screws at the bottom to facilitate the screws at the bottom to fall into the grooves corresponding to the slide rails.

[0023] Specifically, the limiting assembly also includes a fixed ring 43 fixed to the outside of the fixed tube 31, a sliding rod 44 is slidably arranged in the fixed ring 43, the sliding rod 44 extends into the rotating tube 41 and is fixedly connected to a guide block 45, a spiral groove 46 adapted to the guide block 45 is opened in the rotating tube 41, and a return spring 47 is arranged in the rotating tube 41.

[0024] In an embodiment further provided by the present invention, the guide assembly includes a funnel 51 fixed in the storage tank 3, and the output hole at the bottom of the funnel 51 is slightly larger than the diameter of the round end of the screw, ensuring that a single screw passes through the funnel 51 and falls between two rotating rods 52. There are two rotating rods 52 rotatably connected in the storage tank 3, and both rotating rods 52 extend outside the storage tank 3 and are fixedly connected to driven gears 53, and the two driven gears 53 are meshed with each other.

[0025] Furthermore, the discharge port of the funnel 51 is arranged to be an inclined surface, and the rotating rod 52 is arranged to be inclined. When the tip of the screw falls between the two rotating rods 52, the screw will slide directly on the rotating rod 52 and fall into the fixed tube 31. When the round end of the screw falls between the two rotating rods 52, the screw will be reversed due to gravity, so that the extreme end of the screw is rotated directly to the two rotating rods 52, thereby realizing adaptive discharge of the screw.

[0026] Furthermore, the storage tank 3 is rotatably connected to a universal joint 54 on the outside, one end of the universal joint 54 is fixedly connected to the rotating tube 41, and the other end of the universal joint 54 is fixedly connected to a driving gear 55, and the driving gear 55 is meshed with a transmission gear 58 on the outside, and the transmission gear 58 is outside any driven gear 53. By setting the transmission gear 58, it is avoided that the driving gear 55 is meshed with two driven gears 53 at the same time to cause motion interference.

[0027] In the embodiment provided by the present invention, the guide assembly also includes a connecting plate 56, which is rotatably connected to the universal joint 54 and any rotating rod 52. A transmission rod 57 is rotatably connected to the connecting plate 56, and the end of the transmission rod 57 is rotatably connected to the transmission gear 58.

[0028] The solution further provided by the present invention also includes multiple clamping plates 6 slidably arranged on the turntable 2, and the clamping plates 6 are driven separately by multiple driving components to clamp the slide rails at the same time. The driving components include a bidirectional screw 71 rotatably arranged in the turntable 2, and the two clamping plates 6 located on the same side are threadedly connected to the outside of the bidirectional screw 71, and the outside of the bidirectional screw 71 is fixedly connected to a driven bevel gear 72.

[0029] In the present invention, the driving assembly also includes a connecting rod 73 rotatably connected to the turntable 2 , the top end of the connecting rod 73 is fixedly connected to a driving bevel gear 76 meshing with the driven bevel gear 72 , and the bottom end of the connecting rod 73 is fixedly connected to a second gear 74 .

[0030] In the solution further provided by the present invention, a plurality of racks 75 are fixedly connected to the top of the workbench 1, and the racks 75 mesh with the second gear 74. The heights of the racks 75 on the same side are different. When the gear rotates, it only meshes and rotates with the corresponding rack 75, and does not mesh with other racks 75 to avoid motion interference. The tooth direction of the rack 75 when the slide rail rotates to the direction of the storage tank 3 is opposite to the tooth direction of the rack 75 when the slide rail rotates out of the storage tank 3, so that when the gear rotates to the direction of the storage tank 3, the positive rotation drives the clamping plates 6 closer to each other, and when the gear rotates out of the storage tank 3, the reverse rotation drives the clamping plates 6 away from each other.

[0031] When in use, the slide rail is placed on the guide plate 21 away from the storage tank 3, and the turntable 2 is driven to rotate by the driving device, driving the gears to rotate synchronously (with Figure 6 As a reference), when the gear rotates and meshes with the corresponding rack 75, the gear rotates, and the gear rotation drives the connecting rod 73 to rotate synchronously, so that the active bevel gear 76 rotates, driving the driven bevel gear 72 to rotate, so that the bidirectional screw 71 rotates synchronously, so that the two clamping plates 6 on the bidirectional screw 71 approach each other to clamp the slide rail; The screws are input into the storage tank 3. A single screw passes through the hole of the funnel 51 and enters between the two rotating rods 52. The rotating rods 52 are set as inclined surfaces so that the screws falling on the rotating rods 52 always keep the tip facing downwards. Then the screws slide off the rotating rods 52 and fall into the fixed tube 31. The screws are limited by the protrusion of the limiting plate 42 at the bottom and rotated into the fixed tube 31. After the turntable 2 rotates the slide rail to the bottom of the storage tank 3, the storage tank 3 is driven to move, the fixed tube 31 is moved to the hole of the slide rail that needs to be welded and then moves downward. When the sliding rod 44 abuts against the slide rail and continues to move downward, the sliding rod 44 is pushed to move upward, driving the guide block 45 to move synchronously, so that the reset spring 47 is compressed, and the rotating tube 41 is rotated under the limit of the spiral groove 46, driving the two limit plates 42 to rotate, so that the concave part of the bottom limit plate 42 rotates into the rotating tube 41, thereby unlocking the bottom screw, and at the same time, the convex part of the top limit plate 42 rotates into the rotating tube 41, limiting the screw above the bottom screw, so that only the bottom screw falls into the hole of the slide rail, and the welding joint 22 is welded; When the rotating tube 41 rotates, the universal joint 54 is driven to rotate synchronously, so that the driving gear 55 rotates, and the two driven gears 53 are driven to rotate synchronously through the transmission gear 58, so that the two rotating rods 52 rotate synchronously, thereby assisting the screw to slide. When the gear does not rotate, the rotating rod 52 does not rotate, increasing the friction between the screw and the rotating rod 52, slowing down the sliding speed of the screw, and avoiding accumulation; After welding is completed, the storage tank 3 moves up, and the sliding rod 44 is pushed down by the reset spring 47, driving the rotating tube 41 to reverse and reset, so that the limit plate 42 rotates, and the convex part of the limit plate 42 at the bottom is rotated into the rotating tube 41 to limit the screw, and the above operation is repeated.

[0032] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
